They're famous, yes. And good-looking, mostly. Not to get all fashion-police or anything, but these unfortunately dressed men taught us all a little bit about the occasionally important upgrade.

Robert Pattinson

Robert Pattinson

Undoubtedly, he is one of the biggest stars on earth and, for a certain subset of vapmiricly inclined boys and girls, its biggest sex symbol. Not that Pattinson doesn't try to dissuade them of it — we've yet to see the man step out of his coffin with anything resembling a comb so much as touching his hair. The actor has admitted he's not big on bathing, and he most certainly prefers rather ratty, mismatched clothes. Pattinson even manages to make the smartest of suits look disheveled. If we could give Mr. Pattinson two pieces of advice on how to transition from tween heartthrob to legitimate actor and public figure it would be these: tuck in the shirt and wash that hair.

The Suggestion: Get a new hair stylist — a messy, choppy main can be a signature, but no one should be remembered for sporting a rats' nest. Also, tuck in the shirt.

The Takeaway: Looking effortless takes a lot of effort, so pay attention to details like grooming, fit, and, you know, showering. Start with a good haircut and work your way down.

Russell Brand

Russell Brand

He may play the same character onscreen as he does off it, but, hey, the man-child has made it big by starring in Judd Apatow cash cows, writing two booky wookies, sticking with stand-up, and, you know, marrying Katy Perry. We get it: Russell Brand is a performance artist and the world is his stage. All we're asking is that he buttons one more button on his shirt. Just one and we'll leave him alone.

The Suggestion: You're married — might be time to start separating Dr. Jekyll from Mr. Hyde. Even a little.

The Takeaway: Being comfortable in your own skin — and clothes — is the best way to exude confidence. Unbuttoning no more than two buttons of a proper dress shirt is the best way to exude good taste.
